IN SPACE - AUGUST 8: In this handout image provided by NASA and released on August 8, 2012, a comparison shows a view through a Hazard-Avoidance camera on NASA's Curiosity rover before and after the clear dust cover was removed. Both images were taken by a camera at the front of the rover. Mount Sharp, the mission's ultimate destination, looms ahead. The view on the left, with the dust cover on, is one quarter of full resolution, while the view on the right is full resolution. (Photo by NASA/JPL-Caltech via Getty Images)
